I was 'supposedly' abused as a child, would that have broken

I was supposedly abused by my dad when i was 3 an a half, it was my mum who told me that it happened but now i'm begginging to question a lot of what she told me.I want to know if, if he'd abused me at that age, would it have broken my hymen? the other thing i wanted to ask is, does it grow back? because I remember an event when I was 13 i was moving some heavy furniture, and I had a short sharp pain 'down there' and when i went to the toilet later on, i had a little bit of blood in my knickers.

I'm in the process of trying to get to the bottom of all of the mess that my mums created. It would really help if someone could give me some good advice.

Also, would a docter refuse to do a medical examination of a child that he thought had been abused?
